Description
Summary of the bug:
I'm using ffmpeg to convert files to HLS format and found a file where audio seems to be corrupted after convertion.
How to reproduce:
% ffmpeg -i https://lp-us-vod-com.storage.googleapis.com/directUpload/7c5a68zgc5s6gmsl -c:a copy -c:v copy -f hls -hls_list_size 0 -hls_playlist_type vod -hls_segment_type mpegts -hls_time 10 -y index.m3u8
% ffprobe -loglevel warning -show_format -show_streams -print_format json index0.ts
{
[mpegts @ 0x13de04490] start time for stream 1 is not set in estimate_timings_from_pts
[mpegts @ 0x13de04490] stream 1 : no TS found at start of file, duration not set
[mpegts @ 0x13de04490] Could not find codec parameters for stream 1 (Audio: aac ([15][0][0][0] / 0x000F), 0 channels): unspecified sample format
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
